Citation: R v AA (a pseudonym) [2024] NSWSC 409
Court: Supreme Court of New South Wales
Date: 18 April 2024
Judge: Huggett J
Background
The offender, referred to by pseudonym, was born in the United Kingdom in 2002 and moved to Australia at age seven. In mid-2019, at age 16, she began a volatile and mutually violent relationship with the father of her child. She fell pregnant in late 2019, and her daughter, Baby A, was born in August 2020. From early in the pregnancy, and increasingly after the birth, the offender displayed signs of significant mental health deterioration, including suicidal ideation, self-harm, and what clinicians queried as postnatal depression and possible borderline personality disorder.
On 19 July 2021, when Baby A was 11 months old, the offender smothered her. Paramedics revived Baby A, but neurological assessments the following two days confirmed the absence of spontaneous breathing and cranial nerve function. On 21 July 2021, on the recommendation of treating clinicians, Baby A was removed from a ventilator and died shortly afterwards.
The offender pleaded guilty to murder under s 18(1)(a) of the Crimes Act 1900 (NSW). A separate offence of using an offensive weapon with intent to intimidate, committed against the father on 8 March 2021, was taken into account on a Form 1. That earlier incident involved the offender confronting the father with a kitchen knife during an argument.
Legal Issues
- What was the appropriate sentence for murder, having regard to the standard non-parole period of 25 years and the objective seriousness of the offence?
- To what extent did the offender's mental health impairments reduce her moral culpability and affect the weight to be given to general deterrence and denunciation?
- What discount applied for the early guilty plea?
- Did special circumstances exist to justify departing from the statutory ratio between the non-parole period and the balance of term under s 44 of the Crimes (Sentencing Procedure) Act 1999 (NSW)?
- How should the Form 1 offence affect the overall sentence?
Decision
Huggett J sentenced the offender for murder, treating it as the principal offence and taking the weapons offence into account on the Form 1. The court found that the additional offence warranted only a slight increase to the sentence, given that both offences arose while the offender was labouring under the same mental health impairments and because the need to address personal deterrence and denunciation was accordingly reduced.
The court found that the offender's mental health impairments, which were operative at the time of both offences, were significant factors in assessing moral culpability. Those impairments made the offender an inappropriate vehicle for general deterrence and reduced the weight to be afforded to denunciation. The court nonetheless acknowledged the profound seriousness of taking the life of an infant, and that full-time imprisonment was the only appropriate penalty.
A 25% discount was applied to the sentence to reflect the utilitarian value of the early guilty plea, consistent with the principle that a timely plea facilitates the administration of justice. The court also found special circumstances warranting a departure from the statutory non-parole period ratio, based on the offender's age, the fact that this was her first time in custody, the nature and extent of her mental health impairments, and the need for extended supervision and support on release to assist rehabilitation.
The court expressly balanced competing sentencing purposes: punishment and accountability on one side, and rehabilitation, youth, and community protection through successful treatment on the other. The non-parole period imposed was described as the minimum justice required after synthesising all relevant considerations.
Orders Made
- The offender was convicted of murder.
- Taking into account the Form 1 offence and applying a 25% guilty plea discount, the offender was sentenced to 12 years and 3 months imprisonment, commencing 1 March 2022 and expiring 31 May 2034.
- A non-parole period of 8 years was set, expiring 28 February 2030.
- Pursuant to s 25C of the Crimes (High Risk Offenders) Act 2006 (NSW), the offender was advised of the existence of that Act and its application to her murder conviction; her legal representatives were directed to advise her of its implications.
Key Takeaways
-
Significant mental health impairments, where operative at the time of the offence, can reduce moral culpability, diminish the weight given to general deterrence and denunciation, and influence the overall sentencing outcome, even in cases of the utmost seriousness such as the murder of an infant.
-
Special circumstances under s 44 of the Crimes (Sentencing Procedure) Act 1999 (NSW) were established by the combination of the offender's youth, her first period of custody, the nature of her mental health impairments, and her need for ongoing therapeutic support and post-release assistance.
-
A 25% discount for an early guilty plea was applied on the basis that it facilitated the administration of justice, consistent with the approach in cases such as DS v R; DM v R (2022) 109 NSWLR 82.
-
Where a Form 1 offence arises from the same mental health context as the principal offence, the sentencing court may limit the additional weight it attracts, particularly where personal deterrence and denunciation are already reduced in significance.
-
Murder carries a standard non-parole period of 25 years under the applicable NSW legislation, but that standard may be departed from where objective seriousness and subjective circumstances, including mental impairment and youth, collectively justify a lesser non-parole period.
